FESTO電磁閥上海供應(yīng)MFH-5/3E-1/4-B：FESTO電磁閥從原理上分為三大類：1,、直動式電磁閥：原理：通電時,，電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，閥門打開,；斷電時,，電磁力消失，彈簧把關(guān)閉件壓在閥座上,，閥門關(guān)閉,。特點：在真空、負壓,、零壓時能正常工作,，但通徑一般不超過25mm。2、分步直動式電磁閥：原理：它是一種直動和先導(dǎo)式相結(jié)合的原理,，當入口與出口沒有壓差時,，通電后，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起,，閥門打開,。當入口與出口達到啟動壓差時，通電后,，電磁力先導(dǎo)小閥,，主閥下腔壓力上升，上腔壓力下降,，從而利用壓差把主閥向上推開,；斷電時，先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動關(guān)閉件,，向下移動,，使閥門關(guān)閉。特點：在零壓差或真空,、高壓時亦能可*動作,，但功率較大，要求必須水平安裝,。3,、先導(dǎo)式電磁閥：原理：通電時，電磁力把先導(dǎo)孔打開,，上腔室壓力迅速下降,，在關(guān)閉件周圍形成上低下高的壓差，流體壓力推動關(guān)閉件向上移動,，閥門打開,；斷電時，彈簧力把先導(dǎo)孔關(guān)閉,，入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差,，流體壓力推動關(guān)閉件向下移動，關(guān)閉閥門,。特點：流體壓力范圍上限較高,，可任意安裝（需定制）但必須滿足流體壓差條件。電磁閥從閥結(jié)構(gòu)和材料上的不同與原理上的區(qū)別,，分為六個分支小類：直動膜片結(jié)構(gòu),、分步直動膜片結(jié)構(gòu)、先導(dǎo)膜片結(jié)構(gòu),、直動活塞結(jié)構(gòu),、分步直動活塞結(jié)構(gòu),、先導(dǎo)活塞結(jié)構(gòu)。MFH-5-1/8-SMFH-5-1/4-SMFH-3-1/8-SEUMFH-5-PK-3-LMFH-3-3/4MFH-3-1/4-SMFH-5-3/8-L-BMFH-5/2-D-1-CMFH-5/3G-D-1-CMFH-5/3E-D-1-CMFH-5/3B-D-1-CMFH-5/2-D-1-FR-CMFH-5/2-D-2-S-CMFH-5/3G-D-2-S-CMFH-5/3E-D-2-S-CMFH-5/3B-D-2-S-CMFH-5/2-D-3-S-CMFH-5/3G-D-3-S-CMFH-5/3E-D-3-S-CMFH-5/3B-D-3-S-CMFH-5/2-D-2-FR-CMFH-5/2-D-3-FR-CMFH-5/2-D-2-CMFH-5/3G-D-2-CMFH-5/3E-D-2-CMFH-5/3B-D-2-CMFH-5/2-D-3-CMFH-5/3G-D-3-CMFH-5/3E-D-3-CMFH-5/3B-D-3-CMFH-5/2-D-1-S-CMFH-5/3G-D-1-S-CMFH-5/3E-D-1-S-CMFH-5/3B-D-1-S-CMFH-5-1/4-BMFH-5-1/4-S-BMFH-5/2K-FR-NAMFH-5/2-D-1-FR-S-CMFH-5-3/8-BMFH-5-3/8-S-BMFH-5/3G-3/8-BMFH-5/3E-3/8-BMFH-5/3B-3/8-BMFH-5-1/8-BMFH-5-1/8-S-BMFH-5/3E-1/4-BMFH-5/3G-1/4-BMFH-5/3B-1/4-BMFH-5/3E-1/8-BMFH-5/3G-1/8-BMFH-5/3B-1/8-BMFH-5-1/8-L-BMFH-5-1/8-L-S-BMFH-5/3G-1/8-S-BMFH-5/3E-1/8-S-BMFH-5/3B-1/8-S-BMFH-5/3G-1/4-S-BMFH-5/3E-1/4-S-BMFH-5/3B-1/4-S-BMFH-5-1/4-L-BMFH-5/3G-3/8-S-BMFH-5/3E-3/8-S-BMFH-5/3B-3/8-S-BMFH-5-3/8-L-S-BMFH-5-1/4-L-S-BMFH-5-1/2-SMFH-5-PK-3MFH-3-M5MFH-2-M5MFH-3-1/8-EXMFH-3-1/4-EXMFH-3-1/2-EXMFH-3-1/8-S-EXMFH-3-1/4-SMFH-3-1/2-S-EXMFH-5-1/8-EXMFH-5-1/4-EXMFH-5-1/2-EXMFH-5-1/8-S-EXMFH-5-1/4-S-EXMFH-5-1/2-S-EXMFH-5-1/8-B-EXMFH-5-1/4-B-EXMFH-5-3/8-B-EXMFH-5-1/8-L-B-EXMFH-5-1/4-L-B-EXMFH-5-3/8-L-B-EXMFH-5-1/8-S-B-EXMFH-5-1/4-S-B-EXMFH-5-3/8-S-B-EXMFH-5-1/8-L-S-B-EXMFH-5-1/4-L-S-B-EXMFH-5-3/8-L-S-B-EXMFH-5/3G-1/8-B-EXMFH-5/3G-1/4-B-EXMFH-5/3G-3/8-B-EXMFH-5/3G-1/8-S-B-EXMFH-5/3G-1/4-S-B-EXMFH-5/3G-3/8-S-B-EXMFH-5/3E-1/8-B-EXMFH-5/3E-1/4-B-EXMFH-5/3E-3/8-B-EXMFH-5/3E-1/8-S-B-EXMFH-5/3E-1/4-S-B-EXMFH-5/3E-3/8-S-B-EXMFH-5/3B-1/8-B-EXMFH-5/3B-1/4-B-EXMFH-5/3B-3/8-B-EXMFH-5/3B-1/8-S-B-EXMFH-5/3B-1/4-S-B-EXMFH-5/3B-3/8-S-B-EXMFH-5/2-D-1-C-EXMFH-5/2-D-2-C-EXMFH-5/2-D-3-C-EXMFH-5/2-D-1-S-C-EXMFH-5/2-D-2-S-C-EXMFH-5/2-D-3-S-C-EXMFH-5/2-D-1-FR-C-EXMFH-5/2-D-2-FR-C-EXMFH-5/2-D-3-FR-C-EXMFH-5/3G-D-1-C-EXMFH-5/3G-D-2-C-EXMFH-5/3G-D-3-C-EXMFH-5/3G-D-1-S-C-EXMFH-5/3G-D-2-S-C-EXMFH-5/3G-D-3-S-C-EXMFH-5/3E-D-1-C-EXMFH-5/3E-D-2-C-EXMFH-5/3E-D-3-C-EXMFH-5/3E-D-1-S-C-EXMFH-5/3E-D-2-S-C-EXMFH-5/3E-D-3-S-C-EXMFH-5/3B-D-1-C-EXMFH-5/3B-D-2-C-EXMFH-5/3B-D-3-C-EXMFH-5/3B-D-1-S-C-EXMFH-5/3B-D-2-S-C-EXMFH-5/3B-D-3-S-C-EXMFH-3-3/4-EXMFH-3-3/4-S-EXMFH-5-1/4MFH-5-1/2MFH-3-1/8MFH-3-1/8-SMFH-3-1/4-SMFH-3-1/2-SMFH-3-1/2MFH-3-1/4FESTO電磁閥上海供應(yīng)MFH-5/3E-1/4-B德國費斯托電磁閥華東代理
